I guess, with the features you are looking for on a 1600 router, you should upgrade your flash memory to minimum 12MB. With the Software Advisor tool I could get a list all the Cisco IOS images which you could upload for the features you have mentioned. It is available at:

http://www.cisco.com/cgi-bin/Support/CompNav/CN1.pl?HMajorRelease=&HFeatSelected=449%7C485%7C730%7C17%7C205%7C681&HReleaseNumber=All&HReleaseId=-1&HPlatformFamilyName=1600&HPlatformFamilyId=12&HFeatureSetName=NS&HFeatureSetId=0&HRN_Given=1&HPF_Given=...

The IOS which you have currently on your 1600 router is not enough to have the traffic shaping, llq and other stuff. The minimum IOS version you would require is:

12.2(2)T which requires 4MB Dram and 12MB flash. For more details you can refer the link given above.

And as far as the 805 router is concerned, I do not think that frame relay traffic shaping is supported. The rest are supported from 12.1(5)T onwards.This requires 8 MB Dram and 8MB flash. The same can be verified on the Sofware Advisor.
